A hydrophobic ligand binds to a(n) _______, whereas a hydrophilic ligand binds to a(n)_________. a. agonist receptor; antagonic receptor b. transmembrane receptor; intracellular receptor c. antagonist receptor; agonist receptor d. intracellular receptor; transmembrane receptorRelaying a message from a receptor protein to a molecule that performs a specific function within a cell is called ______. selective permeability signal transduction inhibition self-recognition
- Which of the following are methods of cellular signaling? Select one: a. All the answers are correct. b. Connections through fibers of the ECM from one cell to another c. Ligand binding to a receptor in the cell membrane d. Desmosomes ‘pulling’ one cell to another e. Lipid or gas ligand binding to an intracellular receptorYou can choose one or more than one option Gap junctions in animal cells permit: Adjacent cells to adhere strongly to each other Adjacent cells to communicate. Adjacent cells to form a water-tight (occlusive) barrier between their membranes. Second messengers produced in one cell to rapidly diffuse into and stimulate events in surrounding cells. The rapid exchange of proteins such as histones between adjacent cellsA protein changes shape only once, and allows many molecules of one type to pass through the membrane. These molecules are traveling from high concentration to low concentration. What is this protein? A pump A uniport A channel A symport An antiport
- Which of the following is not a constituent of a cell’s proteome?a. An enzymeb. A motor proteinc. A receptor in the plasma membraned. An mRN AThe movement of signaling molecules such as Ca2+ and cAMP from cell to adjacent cell coordinates the responses of cells in tissues. This is achieved by aggregation to which of the following cell adhesion proteins?A) CadherinsB) ConnexinsC) IntegrinsD) Intercellular adhesion molecules (ICAM)E) SelectinsThe main function of plasma membranes is to ________. a. physically protect the cell b. separate the internal environment of the cell from the environment c. ensure the cell properly communicates with stimuli
- Can a cell have multiple responses to one stimulus? A) Yes, such as a second messenger activating a kinase and a transcription factor B) No, one stimulus = one response. C) Yes, but only if the stimulus activates two different types of receptors, like a GPCR and a protein kinase receptor at the same timeA cell releases a ligand that travels through the extracellular matrix to a nearby target cell. There, the ligand binds to a receptor on the target cells membrane. This is an example of _______ signaling using a _______ ligand. paracrine ; hydrophobic paracrine ; hydrophillic endocrine ; hydrophobic endocrine ; hydrophillic autocrine ; hydrophobic autocrine ; hydrophillicCarbon monoxide is a deadly gas. This is due to its quick activation of specific signaling pathways in cells of our body. Since this is a gas, it most likely uses.... Select one: a.
